Pedological → It is formed from "pedon" (from Greek "pedon", meaning ground or soil) and "-logical" (from Greek "logia", meaning study or science). The word "pedological" refers to the scientific study of soils.
Think of 'pedon' meaning ground or soil, and '-logical' meaning study — so pedological is all about the study of soil.
